THIRD-POINT SUSPENSION-HANGER.

Specification of Letters Patent.

Patented J uiy 11, 1916.

Application filed November 15, 1915` Serial No. 61,660.

To (//l whom. it may concern.

Be it known that I, FREDERICK J. Scunounun, a citizenot' the United States, residing at Cleveland, in the county of Cuyahoga and State/of Ohio. have invented certain new and useful Improvements in i'llhirddoint Siispensioil-Hangers, of which the following is a specification.

The present invention relates to third point suspension hangers for trussed brake beams. and the object of the` invention is to proviih` such suspension hangers tor use on existing brake beams, without the require ment ot' any special construction ot' the strut or the tension member bearing, not even as mueh as the drillinpr of a 4single. hole therein.

It has been customary, when a third point hanger is required, to provide an eyclet on the .solid metal of the bralte tulerum right' This is generally the casel when the full-ruins are made of east mal from the start.

terial. lu many eases. l'uleiunlsl which are not provided with such an eyel'et from the beginning. areI afterward `supplied with a third point suspension hanger, either a torging` or a casting. vhieh is riveted or bolted to the brake beam l'ulerum. This requires some fitting of the brake beam which necessitatesl the removal thereotl to perform the machining. This is entirely unnecessary with applicantsl hanger, which can be attached to the brake beam without any preliminary fitting` and withoutremovingr lthe beam from the ear.

ln the aeeomparrving drawing, one enr-- bodiment of the invention has been' illustrated.

Figure l is a side view of the third point suspension hanger and the appurtenairt part of a brake beam on whichit is assembled; Fig. 2, a front elevation of the detached hanger; Fig. 3, an end view partly nl seetion of Fig. 1, seen from the left and Fig. 4 is a plan view of the detached hanger.

The fulcrum of the brake-beam here illustrated is provided with two arms 10 and 11 of rectangular cross section and a solid seat 12 for the tension member 1.3.

The third point suspension hanger is preferably made in one piece from round stock which is bent as illustrated. The middle or saddle portion 14 with the two perpendicular sides 15, 1G form a loop, which is constructed to rde'onvthe ton edge of the fulcrum arm 10 and Contact with the protruding side portions of the fulcrum. The sides 15, 1G are continued by the elbows 17, 1S, which reach forward so as to support the tension member 13 on either side of the seat 12. Lastly the two ends are bent round to form eyelets 19, 20, whic constitute bearingsl for a bolt or pin connecting thev hanger with a suspension rod or chain. It will be noticed` by referring` to the plan view, that the distance between the eyelets is less than the width of the `loop 14, 15, 16. The center line of the eyelets is on the `same level as the axis of the tension member 13 with the parts` in working position as seen in Fig. 1.

It has been found most admtageous to so construct the hanger, that the center ot gravity of tbe fulcrum and. as a consev quenee. of the entire brake beam, falls in the intersection of the central vertical plane between the two eyelets 19, 20, with the horizontal plane through the center line of the eyelets. n this manner the brake beam will be evenlyv balanced, without any tendency ot tilting. one way or another.

lu assembling the parte` it will only be' necessary to spring the eyelets over the seat 112 to the rear of the tension member 13, to swing the eyelets forward under the tension member until the latter rests in the elbows 15. 1G. when the saddle 14 simultaneously seats on top of the brake beam fulerum. lVlien the hanger subsequently is attached to its suspension rod by means of passing a bolt through the eyelets, the hanger will be 4firmly secured on the brake fulcrum without any additional bolts, rivets, or clamps, and no machining er fitting whatsoever will be necessary on the brake beam.

Although the hanger has here been shown as made of round section material, other sections such as square, rectangular, hexagonal, etc., might be used equally Well.

I claim 1. A third point suspension hanger for brake beams comprising a bar of uniform section bent to form a Saddle, two elbows and two eyelets in such a. manner that the saddle rides on top of the brake beam, while the tension member of the brake beam rests in the elbows and the eyelets extend beyond said tension member in the longitudinal direction of the brake beam fulcrum.

Q. A third point suspension hanger for brake beams, said hangercbmprising a saddle, elbows and eyelets,- saidA saddle and elbows being shaped to firmly `engage the ulcrum and the tension member of the brake beam, the eyelets beingadapted' for attachment to a suspensionxrnember.

3. A third point suspension hanger for brake beams, said hanger comprisin a sadxdle, elbows and eyelets, said sad le and elbows, being'shaped to firmly engage the fulliijurn and the tension member ofthe briga,I e beam, the eyelets being adapted. for atvgchment to` a. suspension member;A said ey'e ets being positioned beyond the tension member, in the longitudinal direction of said fulc-rum.

4. A third point suspension hanger for brake beams, said-hanger comprising a sad dle, elbows and eyelets, said saddle and elbows bein shaped to firmly engage the fulcrjum an the tension member'ot' the brake beam, the eyelets being' adapted ffor,

fulcrum, and 1n such a manner that the cen elbows being `sha'ped to firmly engage the A fulcrum and the tension member ofA the brake beam, the eyelets being adapted for attachment to a suspensionA member, said eyelets bein positioned beyond the tension member in t e longitudinal Adirection of said fuicruni, and in such a'mannerthat the ceny 'jter of gravity of the brake beam' lfalls in the intersection of the vertical and horizontal planes which run throu h the' longitudinal axis of the hanger and t e centerline' of the eyelets respectively with the parts in worky ing position.
